It's an excellent idea @tmigot, I didn't find the time to look at `SparseMatricesCOO.jl` but we should use it as a dependency of `NLPModelsJuMP.jl`.

@bharswami I cross-compiled SPRAL on Windows for you: [SPRAL.v2023.9.7.x86_64-windows.tar.gz](https://github.com/ralna/spral/files/12679474/SPRAL.v2023.9.7.x86_64-windows.tar.gz) You will find static and shared libraries (`libspral.a` and `libspral.dll`) as well as all dependencies required by SPRAL (`deps` folder).

MinGW generates static libraries on Windows as `*.a` but you can rename them `*.lib`.

Can you try with the dynamic shared library? Ipopt is compiled with `libspral.dll` in Julia and it's working.

Can you also provide your compilers (C, C++ and Fortran)?

Oh, you need the import libraries (.lib or .dll.a) and not static libraries .a. I can send you the .dll.a files but you must use `gfortran` because I cross-compiled with...

[SPRAL.v2023.9.7.x86_64-w64-mingw32-libgfortran5.tar.gz](https://github.com/ralna/spral/files/12680863/SPRAL.v2023.9.7.x86_64-w64-mingw32-libgfortran5.tar.gz) No, only gcc / gfortran / g++ is available in the cross-compiler.

Yes, I can. I hope that it will help you. [spral.zip](https://github.com/ralna/spral/files/12689953/spral.zip)

@bharswami Can you try to compiler SPRAL with the new Meson build system on Windows?

Can you build and test SPRAL on your windows PC with the meson build system? https://github.com/ralna/spral#installation
